WlRE-COlLlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 393,920, dated December 4, 1888.

Application filed September 10, 1888- Serial No. 285,067. (No model.)

To all whmn it may concern.-

Be it known that I, ALVA OWEN, a citizen of the United States, residing at Chicago, in

ing an especial spring which constitutes the blank out of which is produced acertain spring-clamp, which latter I employ in the construction of. an electric belt secured to me by Letters Patent of'the United States No.

368,546, dated the 16th day of August, 1887.

In the drawings, Figure 1 is a plan view of my improved wire-coiling machine with a blank in position as it appears before the commencement of the coiling operation; Fig. 2, a side elevation of the same, illustratingthe relative initial positions of the parts with a blank inserted; Fig. 3, a similar view of the same, showing the relative final positions of the parts and a spring formed from the blank; Fig. 4, a view in elevation of the side of the machine. opposite that shown in Figs. 2 and 3, illustrating the initial relative positionsof the parts in full lines and their final positions in dotted lines; Figs. 5 and 6, broken perspective views of details, and Fig. 7 a detail view of the spring.

A is the frame of the machine, comprising a base portion, B, provided with screw-holes, through which it may be fastened upon a support carrying standards B B which are perforated toward their upper ends to afiord bearings for a shaft, (1, which latter projects beyond the standards at opposite ends. The shaft 0 toward one end fits closely "the bearings provided in the standard B and toward its opposite end is screw-threaded, as shown at I, to fit a corresponding thread provided in the bearing of the standard B. At its end adjacent to the screw-threaded portion t the shaft carries a crank, D.

E is a bed-plate supported vertically on the shaft 0, near the end of the latter, beyond the standard B Theplate E is fixed upon the shaft O to rotate with it, and the part of the shaft which proj ects beyond the-bed-plate is reduced in diameter and shaped in a manner to afford a stud, s, surrounded at the part adjacent to the bed-plate E by a cam-shaped projection, s, as shown in Fig. 5. A guide-plate, r, is rigidly secured to the outer side of the bed-plate in the position shown, and a gage, q, is pivoted at q to render it adjustable toward and from the stud s, for a purpose hereinafter described, and fastened in its adjusted position by a set screw, (1

Adjacent to the guide-plate r, and normally in contact therewith, is a clamp, 19, on the end of a short shaft which passes through the bedplat'e E and carries at its opposite end a handle, preferably in the form of a lever, 19. 'The lever 12- rests normally against the shoulder of a guide-clip, 13 where it is held by a spring, p The clamp p and lever 19 are rigid upon their connecting-shaft, so that when the lever 11 is raised against the resistance of the spring p from its normal position against the shoulder of the guide-clip p it turns the clampingedge of the clamp p away from the adjacent edge of the guide-plate 1', and when the ley'er p is released the spring p causes it and the clamp p to return to their normal positions, respectively, against the shoulder of the guideclip p and the edge of the guide-plate r.

F is an adjustable and removable holder, provided with a shoulder, 0, and an eye, 0', toward one end to fit loosely over the stud s.

'A stud affording a stop, 02, projects from the outer side of the standard B, and a similar stud, also affording a stop, or, projects from the inner side of the bed-plate E, the stops being thus at opposite sides of the frame A. The screw-thread upon the shaft C and correspondiugly-threaded bearing in the standard B cause the shaft as it is rotated to travel forward or backward, depending upon the direction of its rotation within the limits atforded by the stops n and n. The initial position of the bed-plate E is that illustrated in Figs. 1 and 2 and by full lines in Fig. 4 when the crank D is at its nearest approach to the standard B, where it makes contact with the stop 71. The final position of the bed-plate (illustrated in Fig. 3 and by dotted lines in Fig. 4) is reached after nearly a turn and a half of the shaft 0, when the stop 92 comes into contact with the standard B The operation of my improved machine to form the spring X (shown in Fig. 7) from a straight length of wire constituting the blank X is as follows: The clamp p is turned out of contact with the guide-plate r by raising the lever p and a blank, X, inserted between the clamp and guide plate, with one end against the gage q. The lever p is then released, thereby causing the clamp p to bind the blank X tightly against the guide-plate r. The holder F is then adjusted upon the stud s, with its shoulder o resting against the blank X. The operator then grasps the holder with one hand to retain it and the free end of the wire X in a fixed position, and with the other hand operates the crank D to cause the bed-plate E to rotate and bend the wire X near its middle about the pivot or stud .9 until the stop it reaches the standard B when the turning is impeded and the operation com pleted. The holder F and spring X (thus formed) are then removed from the bed-plate l, and the latter is turned back to its initial position to be ready for another operation. The cam .9, (shown in Fig. 5,) though not indispensable, assists in guiding the wire in the formation of the coil. The holder F, though it affords convenient means for steadying the blank during the coiling operation, may, if desired, be dispensed with and the wire held by the fingers of the operator. The spring X constitutes.a blank out of which, as before stated, a certain spring-clamp is made, and improved machinery for performing the latter operation forms the subj eet of a separate eoncurrent application for Letters Patent which was filed by me on the 2d day of August, 1888, and which bears Serial No. $1,795.

\Vhat I claim as new, and desire to secure by Letters Patent, is
